Revision history for Scope-Upper

0.16    2011-09-03 23:00 UTC
        + Add : uplevel($code, @args, $cxt) executes $code with arguments @args
                in the upper context pointed by $cxt.
                This is an XS version of the well-known uplevel() routine from
                Sub::Uplevel. There are a few differences between both
                implmentations that are listed in the documentation.
                The XS version is roughly 10 times faster than the pure-Perl
                version.

0.15    2011-08-24 14:20 UTC
        + Fix : Localizing subroutines in an higher scope will now correctly
                update the method cache.

0.14    2011-02-27 00:00 UTC
        + Fix : [RT #64997] : Compatibility with perl 5.13.10.
                Thanks Dave Mitchell for the notice.
        + Tst : Lengthy tests have been ported to Test::Leaner, making the
                whole test suite about 50% faster.

0.13    2010-12-20 01:00 UTC
        + Fix : [RT #61904] : Stack corruption when using unwind() under
                Devel::NYTProf.
                Thanks Sergey Aleynikov for contributing a fix.
        + Fix : [RT #63378] : Compatibility with perl 5.13.8.
                Thanks Andreas J. K旦nig for bisecting the issue.
        + Tst : Threads tests are now only run on perl 5.13.4 and higher.
                They could segfault randomly because of what seems to be an
                internal bug of Perl, which has been addressed in 5.13.4.
                There is also an environment variable that allows you to
                forcefully run those tests, but it should be set only for
                author testing and not for end users.
